  Patch from Marcelo Vianna <mfvianna at centroin dot com dot br> to get \ 
his modes
    (cage,moebius,morph3d,rubik) working on NVidia under XFree (NVidia
    has a policy to not release code open source and the bug crashes the
    system requiring a hard reset).  Since skewb is similar that was done
    as well by maintainer.
  configure changes for 2.53, added option for .ad installation dir,
     check for xlockrc and pam.
  flag debugged for xpm, do not set byte order for ZPixmap.
    Flag ripples now flow left to right and from bottom to top.
  Combined XLock-jp.ad into XLock.ad
  fontset to use regular (not bold/italic) font/fontset as default,
    fix for sound.c using DEF_PLAY, and a fix for customName
    thanks to Shingo Yamaguchi <shingo at kip dot iis dot toyama-u dot ac dot \ 
jp>.
  nice changes were causing problems, set_priority used instead thanks
    to Felicia Neff <fn at panix dot com>. (VMS still uses nice).
  noof mode added from GLUT demos thanks to Dave Riesz <driesz at cpl dot net>.
  USE_XPM changed to HAVE_XPM to be compatible with xscreensaver.
